ERNST BENJAMIN THORIN, OF STOCKHOLM, SVEDEN.

TRANSPOSING ACTION FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 606,748, dated July 5, 1898.

Application filed November 20,1897. Serial No. 659,322. (No model.) Patented in Germany May 24:, 1S9'7,N0.11,302; in Sweden August 12, 1897,11'0- 8,196, and in England September 13, 1897,11'0. 21,469.

To all whom, it may concern:

Be it known that I, ERNST BENJAMIN THO- RIN, of Stockholm, in the Kingdom of Sweden, have invented a new and Improved Transposing Action for Reed-Organs, of which the following is a full, clear, and exact description.

My invention consists in a transposing action for reed-organs, whereby the transposition can be made at any time, even during the playing on the instrument. Besides, the construction of my improved transposing organ is much more simple and cheaper than any other hitherto known, as will be easily understood from the following description.

The invention forming the subject of this application is the same as that for which Letters Patent were granted me in Sweden August 12,1897,No. 8,196; in Germany May 24:, 1897, No. 11,802, and in Great Britain September 18, 1897, No. 21,469.

On the annexed drawings, Figure l is a plan view, and Fig. 2 a vertical cross-section, of the contrivance. The cells in the reed-boards are not drawn in Fig. 1. Figs. 3 and 4 are also vertical cross sections showing slight modifications in the practical performance of the invention.

Referring first to Figs. 1 and 2, a is the wind-chest. q is the upper board or lid of the wind-chest. f is the reed-board or so-called reed-cell board, which supports the reeds in slots or cells formed therein. cc are valveopenings in the upper board of the windchest. l) b are the reed-valves for controlling the air communication between the windchest and the reed-cells.

The characteristic of my invention is that I make the reed-board or reed-boards movable relatively to the wind-chest in such a manner that the reed-board or reed-boards may slide in their longitudinal direction along the wind-chest. For that purpose I apply the reed boards on an extra board or slide d,which may be moved in suitable guides on the upper board of the wind-chest. According to Figs. 1 and 2 the reed-board is glued on the upper surface of the slide, so that the latter extends under the reed-board between that and the upper board of the wind-chest. In this case the slide (Z must of course be provided with openings 6, which coincide upward with the cells or slots in the reed-board and downward with the valve-openin gs in the upper board of the wind-chest, so that air can pass from a reed-cell through the slide d and the upper board q of the wind-chest when the corresponding reed-valve is open. When the slide is moved lengthwise, its openings, and thus also the cells in the reed-board, which of course partake in the movement, will communicate with other reed-valve openings c in the upper board of the wind-chest. Thus the transposition is effected.

The upper pin-lath g, which is secured to the lath h, glued onto the upper board of the wind-chest, serves, together with the lath h, as guide for that edge of the slide d on which the reed-board is situated, while the other edge of the slide is guided by an angular lath 2', secured to the wind-chest.

In order to still more secure the tightness between the slide d and the upper board of the wind-chest, there may, if necessary, be used springs which press the slide against the wind-chest, thus compensating eventual wearing.

For actuating the slide any suitable lever arrangement may be used which connects the slide or reed-board with a so-called register or stop-knob projecting on the front side of the organ--for instance,above the keys.

Said register may be movable forward and backward or upward and downward or to the right and left. Sometimes I connect the lever arrangement with one or two pedal-levers which may be actuated by the feet. Instead of said lever apparatus a simple arm or handle may be fastened to the slide or reed-board in such a manner that it projects through a horizontal slot in the front side of the casing, so that by moving said arm or handle to the right orleft the slide and reed-board will si multaneously be moved in the same direction. The projecting arm or handle may be actuated by hand or knee. Of course the slide also can be actuated by means of a crank with toothed wheel engaging a rack on the slide or reed-board or by any other suitable means.

When, as shown in the drawings, two slides are used, they must of course be connected ICO 2 I coarse with each other in such a manner as to be moved in exactly the same degree simultaneously when actuated.

The slide (Z need not necessarily extend under the reed-boards; but it may be glued on one or both longitudinal edges of said reed-boards. In such case the openings 0 are dispensed with and the cells or slots in the reed-boards communicate directly with the reed-valve openings. Such a modification is shown in Fig. 3 in vertical section. cl is the slide, and q the board, of the wind-chest. As the reed-board seen from above iswedgeshaped, the slide (1, glued on its non-parallel side, must of course also be wedge-shaped, but contrarily, so that the free edge of the reed-board m ay be parallel with the free edge of the slide. The slide may also consist of a part of the upper board of the wind-chest, so that the valve-openings 0 will partake in the movement of the slide. Such an arrangement is shown in Fig. elin vertical section. q is the upper board of the wind-chost-, and (t is the movable part of it. In this case a special device is necessary for bringing the valves 1) out of contact with the slide when the latter is moved. In the case illustrated said device consists of an eccentrically-pivoted rib 1', which when turned downwardly will act upon the valves Z1, so that all the lattor are opened simultaneously and thus brought out ol contact with the slide in order not to damage the valves or their coverings during the transposition. In this case the slide must of course be made so much longer than the wind-chest as not to be brought out of contact with the side walls of the windchest even when moved to its uttermost position.

It will be seen from the above description and from the drawings that my construction is much more simple and cheaper to man ufacture than any hitherto used, as the usual series of transposing keys or levers and every other expensive means are altogether dispensed with. In fact, my construction is the simplest and cheapest possible, and at the same time its function is very goot'l. and reliable.

I claim- 1. In a reedorgan, a reed-board adapted to slide along the wind-chest.

2. In a reed-organ a reed-cell board adapted to slide along the wind-chest and means [or moving said reed-coll board relatively to the wind-chest.

In a rccd-organ a transposing action con sist-ing of movable reed-board or reed-lmards adapted to slide along the series ot reedvalves.

el. In a reed-organ a transposing action consisting of rced-boarc s movable in guides along the wind-chest and means for moving said. reed-boards by moving a knob or other part, projecting in the front of the organ.

5. In a reed-orgal'i a device :t'or trans msition, consisting of reed-cell boards movable in guides lengthwise upon the upper board of the wind-chest and means for moving said reed-boards in their guides by actuating n stop-knob or such like in front of the-organ.

6. In reed-organs a board or slide adapted to move in guides lengthwise upon the upper board of the wind-chest, a reed-cell hoard fastened on the slide, and slots or openings in the slide, said slots or openings communicating upward with the cells oi the recd-cell board and downward with the rccd valve openings of the upper board of the wiml-clmsl, and means for actuating the slide or reed-cell board [rom the front of the organ.

7'. In reed-organs with movable rced-lmards, the extra boards (a d fastened to the reedboardsff, the guides i i and g, 71, connection between the reed-boards or extra boards, and means for actuating the connected rccdboards or extra boards.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
